Thanks for the info, Pat. It just seemed like the obvious place to go for a stamp. It's self-inking so I am stuck with what I have for now. I can live with it for a while for sure.
I don't sell my stuff - mostly give it away as gifts and I didn't have any real idea of what to make it say anyway. It just says "Handcrafted by" on the top line and then my name on the bottom line. It's definitely a step up from writing my initials by hand with a Sharpie anyway.
It would still be better with ink that didn't run. And I would like to be able to use different colors of ink for different colors of wood. Black works for many but would disappear on walnut. Do you have a link handy for a good online stamp maker?
